BACKGROUND

The present invention relates generally to the field of email, and more particularly to preventing the modification of an email by the recipients of the email.

An email, or electronic mail, is a method of exchanging digital messages from an author to one or more recipients. Email operates across the Internet or other networks. An Internet email message includes three components: the message envelope, the message header, and the message body. The message header contains control information, including, minimally, an originator's email address and one or more recipient addresses. Usually, descriptive information is also added, such as a subject header field and a message submission date/time stamp.

SUMMARY

Aspects of an embodiment of the present invention disclose a method, computer program product, and computing system for preventing the modification of an email by the recipients of the email. A processor receives an indication that an email message is composed. A processor receives an indication that modification of contents of the email message, by one or more recipients of the email message, is to be prevented. A processor converts the contents of the email message from editable text to a non-editable format. A processor sends the converted email message to a recipient.

DETAILED DESCRIPTION

With the current state of email, the recipient of an email can edit the content of the received email when replying or forwarding the email. Embodiments of the present invention recognize that an email that cannot be modified when used as a reference in replying or forwarding may be viewed as more authentic to the person receiving the reply or forward email. Embodiments of the present invention detail an approach that can be used to prevent the modification of an email by the recipients of the email.

Embodiments of the present invention will now be described in detail with reference to the Figures.

FIG. 1 depicts a block diagram of computing system 10, in accordance with one embodiment of the present invention. FIG. 1 provides an illustration of one embodiment and does not imply any limitations with regard to the environments in which different embodiments may be implemented.

In the depicted embodiment, computing system 10 includes server 30. In some embodiments, computing system 10 can send and receive information over a network. The network (not shown) may be a local area network (LAN), a wide area network (WAN) such as the Internet, a cellular data network, any combination thereof, or any combination of connections and protocols that will support communications between server 30 and other computing devices (not shown) that may send information to server 30 and/or receive information from server 30, in accordance with embodiments of the invention. The network may include wired, wireless, or fiber optic connections. Computing system 10 may include additional computing devices, servers, or other devices not shown.

Server 30 may be a management server, a web server, or any other electronic device or computing system capable of processing program instructions and receiving and sending data. In some embodiments, server 30 may be a laptop computer, tablet computer, netbook computer, personal computer (PC), a desktop computer, or any programmable electronic device. In other embodiments, server 30 may represent a server computing system utilizing multiple computers as a server system, such as in a cloud computing environment. In another embodiment, server 30 represents a computing system utilizing clustered computers and components to act as a single pool of seamless resources. Server 30 contains prevent modification program 110. Server 30 may include components, as depicted and described in further detail with respect to FIG. 4.

Prevent modification program 110 prevents the modification of an email by the recipients of the email. In doing so, a user, initially, composes a message. Prevent modification program 110 receives an indication that the message is complete. Prevent modification program 110 receives an indication that the user wants to prevent modification of the message. Prevent modification program 110 converts the message from a text file to a picture file. While a picture file is merely one example, prevent modification program 110 may convert the message from a text file to any type of non-editable file (e.g., a non-editable portable document format (PDF) file). Prevent modification program 110 sends the picture file to a recipient. In the depicted embodiment, prevent modification program 110 resides on server 30. In other embodiments, prevent modification program 110 may reside on another server or another computing device.

FIG. 2 depicts a flowchart of the steps of a prevent modification program, executing within the computing system of FIG. 1, in accordance with an embodiment of the present invention. Prevent modification program 110 prevents the modification of an email by the recipients of the email.

In step 210, a user, initially, composes a message. In one embodiment, the user composes a message by typing a new message within the message body section of an email. In other embodiments, the user composes a message by copying and pasting text into the message body from another source. The message is in the form of text.

In step 220, prevent modification program 110 receives an indication that the message is complete. In one embodiment, prevent modification program 110 receives an indication that the message is complete after a predetermined time period after the user ceases typing in the body of the email. In other embodiments, prevent modification program 110 receives an indication that the message is complete after the user clicks an arbitrary “message complete” button within an email interface. In some embodiments, prevent modification program 110 receives an indication that the message is complete after the user clicks the delivery options button within an email interface, such as Delivery Options 310 within environment 300 in FIG. 3 below. Still, in other embodiments, prevent modification program 110 receives an indication that the message is complete after the user clicks the “Send” button within an email interface, where a default delivery option could be that every email sent would be un-editable.

In step 230, prevent modification program 110 receives an indication that the user wants to prevent modification of the message. In one embodiment, prevent modification program 110 receives an indication that the user wants to prevent modification of the message after the user clicks the prevent modification button within an email interface, such as Prevent Modification 340 within environment 300 in FIG. 3 below. In other embodiments, prevent modification program 110 receives an indication that the user wants to prevent modification of the message after the user types “Prevent Modification” in the heading or body of the email. In some embodiments, prevent modification program 110 receives an automatic indication that the user wants to prevent modification of the message after prevent modification program 110 receives the indication that the message is complete.

In step 240, prevent modification program 110 converts the message from a text file to a picture file. While a picture file is merely one example, prevent modification program 110 may convert the message from a text file to any type of non-editable file (e.g., a non-editable PDF file). In one embodiment, prevent modification program 110 converts the message from a text file to a picture file by taking a screenshot of the message body. In other embodiments, prevent modification program 110 converts the message from a text file to a picture file by using a program (not shown) that is developed to convert files from one version to another version. In some embodiments, the message will appear the same as a normal message in the message body when received by a recipient. In some embodiments, prevent modification program 110, via an email client, makes the text un-editable. For example, if the email is sent to people within the same company (i.e., using company email addresses and a company-wide email client), prevent modification program 110, via the email client, can cause the text to be un-editable to recipients of the email.

In step 250, prevent modification program 110 sends the picture file to a recipient. In one embodiment, prevent modification program 110 sends the picture file to the recipient by copying the picture file into the body of the email. In some embodiments, prevent modification program 110 sends the picture file to the recipient by including the picture file as an attachment. In one embodiment, prevent modification program 110 sends the picture file to the recipient after the user clicks the “Send” button within an email interface. In other embodiments, prevent modification program 110 automatically sends the picture file to the recipient after prevent modification program 110 converts the message from a text file to a picture file.

In FIG. 3, environment 300 depicts an example of an email interface, in accordance with an embodiment of the present invention.

Environment 300 depicts an email interface that includes Delivery Options 310, Prevent Copying 320, Mark Subject Confidential 330, and Prevent Modification 340. In the depicted embodiment, Delivery Options 310 opens up a window, or otherwise gives the user options and parameters, to choose for delivering an email, such as Prevent Copying 320, Mark Subject Confidential 330, and Prevent Modification 340. In the depicted embodiment, Prevent Copying 320 gives the user the option to prevent the receiver from replying or forwarding the sent email. In the depicted embodiment, Mark Subject Confidential 330 gives the user the option to label the email as confidential. In the depicted embodiment, Prevent Modification 340, after implementation of embodiments of the present invention, gives the user the option to allow the receiver to reply or forward the sent email, but prevents the user from modifying the contents of the sent email.

As an example, in step 230 of FIG. 2, prevent modification program 110 may receive an indication that the user wants to prevent modification of the message by the user clicking Prevent Modification 340. Prevent Modification 340 is revealed after the user clicks Delivery Options 310. Additionally, Prevent Copying 320 and Mark Subject Confidential 330 are also revealed after the user clicks Delivery Options 310.

In general, memory 402 can include any suitable volatile or non-volatile computer readable storage media. Cache 403 is a fast memory that enhances the performance of processors 401 by holding recently accessed data, and data near recently accessed data, from memory 402.

Program instructions and data used to practice embodiments of the present invention may be stored in persistent storage 405 and in memory 402 for execution by one or more of the respective processors 401 via cache 403. In an embodiment, persistent storage 405 includes a magnetic hard disk drive. Alternatively, or in addition to a magnetic hard disk drive, persistent storage 405 can include a solid state hard drive, a semiconductor storage device, read-only memory (ROM), erasable programmable read-only memory (EPROM), flash memory, or any other computer readable storage media that is capable of storing program instructions or digital information.

The media used by persistent storage 405 may also be removable. For example, a removable hard drive may be used for persistent storage 405. Other examples include optical and magnetic disks, thumb drives, and smart cards that are inserted into a drive for transfer onto another computer readable storage medium that is also part of persistent storage 405.

Communications unit 407, in these examples, provides for communications with other data processing systems or devices. In these examples, communications unit 407 includes one or more network interface cards. Communications unit 407 may provide communications through the use of either or both physical and wireless communications links. Program instructions and data used to practice embodiments of the present invention may be downloaded to persistent storage 405 through communications unit 407. Prevent modification program 110 may be downloaded to persistent storage 405 of server 30 through communications unit 407 of server 30.

I/O interface(s) 406 allows for input and output of data with other devices that may be connected to each computer system. For example, I/O interface 406 may provide a connection to external devices 408 such as a keyboard, keypad, a touch screen, and/or some other suitable input device. External devices 408 can also include portable computer readable storage media such as, for example, thumb drives, portable optical or magnetic disks, and memory cards. Software and data used to practice embodiments of the present invention, e.g., prevent modification program 110, can be stored on such portable computer readable storage media and can be loaded onto persistent storage 405 of server 30 via I/O interface(s) 406 of server 30. I/O interface(s) 406 also connect to display 409.

Display 409 provides a mechanism to display data to a user and may be, for example, a computer monitor.
